IDEM's SENSATUS "Intelligent Series" Non Contact Switches have
been developed to provide and maintain a high level of functional
safety whilst providing tamper proof RFID coded activation.
They will connect to most popular standard safety relays to
maintain a PLe/Category 4 Safety level even with switches
connected in series.
They are offered in high specification plastic housings and can be
used in virtually any environment including high pressure cleaning
following contamination from foreign particles.
They have IP69K ingress protection and are suitable for CIP and
SIP cleaning processes.
They are supplied with easy to understand LED diagnostic functions
and provide auxiliary outputs for extra diagnostic signals to PLCs
or computers.
The typical sensing distance "on" is 12mm with wide tolerance to
guard misalignment after setting.
Coding is achieved by using magnetic and radio frequency
techniques, both principles need to be satisfied for the switch to
operate safely
The RFID sensing provides a tamper resistant operation when the
actuator is in the sensing range of the switch.
The SENSATUS switches are available in two versions:
Version 1: TYPE M. Master Code - by series (any actuator will
operate any switch) used when unique door activation is not
required, but the benefit of RFID makes it virtually impossible to
be over-ridden or by-passed by simple means.
Version 2: TYPE U. 32,000,000 Unique Codes. These switches are
factory set and used when UNIQUE activation is required in areas
where there are many interlocked doors and security of individual
areas is required.
